i installed a self driving car project from superdatascience site , when i open the map using terminal after a while the map window close up or it closes directly after i maximize the map window and it gives me this error :

 IndexError: index 620 is out of bounds for axis 1 with size 600

the code i have in the brain ( ai.py file ) is

 class Dqn():

 def select_action(self, state):
 probs = F.softmax(self.model(Variable(state, volatile = True))*100) # T=100
 action = probs.multinomial(num_samples=1)
 return action.data[0,0]

the code i have in the map ( map.py file ) is

class MyPaintWidget(Widget):

 def on_touch_down(self, touch):
 global length, n_points, last_x, last_y
 with self.canvas:
 Color(0.8,0.7,0)
 d = 10.
 touch.ud['line'] = Line(points = (touch.x, touch.y), width = 10)
 last_x = int(touch.x)
 last_y = int(touch.y)
 n_points = 0
 length = 0
 sand[int(touch.x),int(touch.y)] = 1

what should i do or change ??

One of the values being returned by touch.x or touch.y are bigger than the dimensions of the sand array.

You could try adding a try/except block around it and print a useful message - just as an example, as I have no idea what this programme is doing (in the on_touch_down function):

def on_touch_down(self, touch)
...
...
 try:
 sand[int(touch.x), int(touch.y)] = 1
 except IndexError:
 print("Touchdown did not occur within the end-zone! No goal!")
